Hi All
I need a pair (at least) of devises which act like a jack to spread two pillars which are ~500mm apart. Bottle jacks would be ideal but I doubt they're available in such a size. A sash cramp operating in reverse would also do fine. But most that I see are only set up to compress. Some might have a reversable end stop, but the screwing end seems only to work one way. Does anyone know of a sash cramp available that has a usable surface/pad on both sides of the screwing end?
